<p><P>PROBLEM TO BE SOLVED: To perform rolling by deciding rolling pass schedule to make an actual material coincide with the target material and to reduce variation in the actual material. <P>SOLUTION: This method is a rolling method of a steel sheet 1 having a heating stage 5, a rough rolling stage 6 and a finish rolling stage 7, which has a basic calculation stage 17 for calculating a pass schedule taking the target value as a control factor and a calculation stage 18 before rough rolling for performing corrective calculation of the pass schedule taking the actual value as a control factor just before the rough rolling stage 6 and/or an intermediate calculation stage 20 for performing corrective calculation of the pass schedule by taking the actual value as the control factor at n-th pass before the final pass. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
